WARNINGS

MEDICAL ALERT - Airless Spray Wounds

If any uid appears to penetrate your skin, get EMERGENCY MEDICAL CARE AT ONCE. DO NOT TREAT AS A SIMPLE CUT. Tell the doctor exactly what uid was injected. Have him read the following "NOTE TO PHYSICIAN".

HIGH PRESSURE SPRAY CAN CAUSE EXTREMELY SERIOUS INJURY. OBSERVE ALL WARNINGS. THIS SPRAYER IS FOR PROFESSIONAL USE ONLY.

INJECTION HAZARD

FLUIDS UNDER HIGH PRESSURE FROM SPRAY OR LEAKS CAN PENETRATE THE SKIN AND CAUSE EXTREMELY SERIOUS INJURY, INCLUDING THE NEED FOR AMPUTATION. NEVER point the spray gun towards anyone or at any part

of the body. NEVER put hand or ngers over the spray tip. Do not use rag or other materials over your ngers. Paint will penetrate through material and into the hand.

NEVER try to stop or deect leaks with your hand or body. ALWAYS have gun tip guard in place when spraying. ALWAYS lock gun trigger when you stop spraying. ALWAYS remove tip from the gun to clean it. NEVER try to "blow back" paint, it’s not an air sprayer. ALWAYS follow the PRESSURE RELIEF PROCEDURE,

as shown on page 8, before cleaning or removing the spray tip or servicing any system equipment. Be sure equipment safety devices are operating properly before each use. ALWAYS tighten all uid connections before each use.

MEDICAL TREATMENT

If any uid appears to penetrate your skin, get

EMERGENCY CARE AT ONCE. DO NOT TREAT AS A SIMPLE CUT.

• Go to an emergency room immediately.

• Tell the doctor you suspect an injection injury.

• Tell him what kind of material you were spraying with and have him read NOTE TO PHYSICIAN above.

GENERAL PRECAUTION

NEVER alter equipment in any manner. NEVER smoke while in spraying area. NEVER spray highly ammable materials. NEVER use around children. NEVER allow another person to use sprayer unless he is

thoroughly instructed on its' safe use and given this operators manual to read. ALWAYS wear a spray mask, gloves and protective eye wear while spraying. ALWAYS ensure re extinquishing equipment is readily available and properly maintained.

NEVER LEAVE SPRAYER UNATTENDED WITH PRESSURE IN THE SYSTEM. FOLLOW PRESSURE RELIEF PROCEDURES ON PAGE 8.

NOTE TO PHYSICIAN: Injection in the skin is a traumatic injury. It is important to treat the injury surgically as soon as possible. DO NOT DELAY treatment to research toxicity. Toxicity is a concern with some exotic coatings injected directly into the blood stream. Consultation with a plastic surgeon or reconstructive hand surgeon may be advisable.

ALWAYS INSPECT SPRAYING AREA

Keep spraying area free from obstructions. Make sure area has good ventilation to safely remove vapors. NEVER keep ammable material in spraying area. NEVER spray in vicinity of open ame or other sources of ignition. Spraying area must be at least 20 ft. away from spray unit.

SPRAY GUN SAFETY

ALWAYS set safety lock on the gun in "LOCKED" position when not in use and before servicing or cleaning.

DO NOT remove or modify any part of gun. ALWAYS remove spray tip when cleaning. Flush unit with LOWEST POSSIBLE PRESSURE. CHECK operation of all gun safety devices before each

use. Be very careful when removing the spray tip or hose from gun. A plugged line contains uid under pressure. If the tip or line is plugged, follow the PRESSURE RELIEF PROCEDURE as outlined on page 8.TIP GUARD

TIP GUARD

ALWAYS have the tip guard in place on the spray gun while spraying. The tip guard alerts you to the injection hazard and helps prevent accidentally placing your ngers or any part of your body close to the spray tip.

SPRAY TIP SAFETY

USE EXTREME CAUTION when cleaning or changing spray tips. If the spray tip clogs while spraying, engage the gun safety latch immediately. ALWAYS follow the PRESSURE RELIEF PROCEDURE before removing the spray tip to clean it.

NEVER wipe off build up around the spray tip. ALWAYS remove tip & tip guard to clean AFTER pump

is turned off and the pressure is relieved by following the

PRESSURE RELIEF PROCEDURE.

WARNINGS CONTINUED ON NEXT PAGE.........

WARNINGS - CONTINUED

ALWAYS INSPECT SPRAYING AREA

Keep clear of moving parts when starting or operating the sprayer. Do not put your ngers into any openings to avoid amputation by moving parts or burns on hot parts.Precaution is the best insurance against an accident.

When starting the engine, maintain a safe distance from moving parts of the equipment.

Before adjusting or servicing any mechanical part of the sprayer, follow the PRESSURE RELIEF PROCEDURE on page 8, and remove the ignition cable from the spark plug to prevent accidental starting of sprayer.

HOSES

Tighten all uid connections securely before each use. High pressure uid can dislodge a loose coupling or allow high pressure spray to be emitted from the coupling and result in an injection injury or serious bodily injury.

Use only hose that has a spring guard. The spring guard helps protect the hose from kinks or other damage which could result in hose rupture and cause an injection injury.

GROUNDING

Ground the sprayer and other components in the system to reduce the risk of static sparking, re or explosion which can result in serious bodily injury and property damage.

ALWAYS GROUND ALL OF THESE COMPONENTS:

1. Sprayer: Connect a ground wire and clamp (supplied) to a true earth ground.

2. Fluid Hose: use only grounded hoses.

3. Spray gun or dispensing valve: grounding is obtained through connection to a properly grounded uid hose and pump.

4. Object being sprayed: according to your local code.

5. All solvent pails used when ushing should only be metal pails which are conductive.

Once each week, check electrical resistance of hose (when using multiple hose assemblies, check overall resistance of unpressurized hose must not exceed 29 megohms (max) for any coupled length or combination of hose lengths. If hose exceeds these limits, replace it immediately.

Never exceed 500 Ft. (150 m.) overall combined hose length to assure electrical continuity.

NEVER use a damaged hose, which can result in hose failure or rupture and cause in injection injury or other serious bodily injury or bodily damage. Before each use, check entire hose for cuts, leaks, abrasion or bulging of cover, or damage or movement of couplings. If any of these conditions exist, replace the hose immediately. Never use tape or any device to try to mend the hose as it cannot contain the high pressure uid. NEVER ATTEMPT TO RECOUPLE THE HOSE. High pressure hose is not recoupleable.

Help prevent damage to the hose by handling and routing it carefully. Do not move the sprayer by pulling it with the hose.

LABELING

Keep all labels on the unit clean and readable. Replacement labels are available from manufacturer.

TOXIC FLUID HAZARD

Hazardous uid or toxic fumes can cause serious injury or death if splashed in eyes or on skin, inhaled or swallowed. Know the hazards of the uid you are using. Store & dispose of hazardous uids according to manufacturer, local, state & national guidelines. ALWAYS wear protective eyewear, gloves, clothing and respirator as recommended by uid manufacturer.

WARNINGS CONTINUED ON NEXT PAGE.........

WARNINGS - CONTINUED

AVOID COMPONENT RUPTURE

This sprayer operates at 3000 psi (205 bar). ALWAYS be sure that all components and accessories have a maximum working pressure of at least 3000 psi to avoid rupture which can result in serious bodily injury including injection and property damage. NEVER leave a pressurized sprayer unattended to avoid accidental operation of it which could result in serious bodily injury. ALWAYS follow the PRESSURE RELIEF PROCEDURE whenever you stop spraying and before adjusting, removing or repairing any part of the sprayer. NEVER alter or modify any part of the equipment to avoid possible component rupture which could result in serious bodily injury and property damage. NEVER use weak or damaged or non-conductive paint hose. Do not allow kinking or crushing of hoses or allow it to vibrate against rough or sharp or hot surfaces. Before each use, check hoses for damage and wear and ensure all uid connections are secure. REPLACE any damaged hose. NEVER use tape or any device to mend the hose. NEVER attempt to stop any leakage in the line or ttings with your hand or any part of the body. Turn off the unit and release pressure by following PRESSURE RELIEF

PROCEDURE. ALWAYS use approved high pressure ttings and

replacement parts. ALWAYS ensure re extinquishing equipment is readily available and properly maintained.

PREVENT STATIC SPARKED FIRE/ EXPLOSIONS

ALWAYS be sure all equipment and objects being sprayed are properly grounded. ALWAYS ground sprayer, paint bucket and object being sprayed. See "grounding" on page 3 for detailed grounding information. Vapors created when spraying can be ignited by sparks. To reduce the risk of re, always locate the sprayer at least 20 feet (6 m.) away from the spray area. DO NOT plug in or unplug any electrical cords in the spray area, which can create sparks, when there is any chance of igniting vapors still in the air. Follow the coating & solvent manufacturers safety warnings and precautions. Use only conductive uid hoses for airless applications. Be sure gun is grounded through hose connections. Check ground continuity in hose & equipment. Overall (end to end) resistance of unpressurized hose must not exceed 29 megohms for any coupled length or combination of hose length. Use only high pressure airless hoses with static wire approved for 3000 psi.

FLUSHING

Reduce the risk of injection injury, static sparking or splashing by following the specic cleaning procedure on page 6 and 8. ALWAYS follow the PRESSURE RELIEF PROCEDURE on page 8. ALWAYS remove the spray tip before ushing. Hold a metal part of the gun rmly to the side of a metal pail and use the lowest possible uid pressure during ushing. NEVER use cleaning solvents with ash points below 140 degress F. Some of these are: acetone, benzene, ether, gasoline, naphtha. Consult your supplier to be sure.

NEVER SMOKE IN THE SPRAYING/CLEANING AREA.

WARNING

Do not use halogenated solvents in this system. The prime valve, 2 gun manifold and most airless guns have aluminum parts and may explode. Cleaning agents, coatings, paints or adhesives may contain halogenated hydrocarbon solvents. DON"T TAKE CHANCES! Consult your material suppliers to be sure. Some of the most common of these solvents are: Carbontetrachloride, Chlorobenzene, Dichloroethane, Dichloroethyl Ether, Ethylbromide, Ethylchloride, Tethrachloethane. Alternate valves and guns are available if you need to use these solvents.

WHEN SPRAYING & CLEANING WITH FLAMMABLE PAINTS OR THINNERS:

1. When spraying with ammable liquids, the unit must be located a minimum of 25 feet away from the spraying area in a well ventilated area. Ventilation must be sufcient enough to prevent the accumulation of vapors.

2. To eliminate electrostatic discharge, ground the spray unit, paint bucket and spraying object. Use only high pressure airless hoses approved for 3000 psi which is conductive.

3. Remove spray tip before cleaning gun and hose. Make contact of gun with bucket and spray without the tip in a well ventilated area, into the grounded steel bucket.

4. Never use high pressure in the cleaning process. USE MINIMUM PRESSURE.

5. Do not smoke in spraying/cleaning area.

GAS ENGINE PRECAUTIONS

Place unit 25 feet away from spraying in ventilated area.

NEVER operate in buildings unless exhaust is piped outside. NEVER allow hose to lay against engine mufers or hot parts. NEVER rell fuel tank while engine is hot or is running.

IMPORTANT: United States Government safety standards

have been adopted under the Occupational Safety & Health Act. These standards, particularly the General Standards, Part 1910, & the Construction Standards, part 1926 should be consulted.

HOW TO FLUSH

1. Be sure the gun safety latch is engaged and there is no spray tip in the gun. Refer to Fig. 2. Refer to your separate instruction manual provided with your gun on its safety features and how to engage safety latch.

2. Pour enough clean, compatible solvent into a large, empty metal pail to ll the pump and hoses.

3. Place the suction tube into the pail or place the pail under the pump.

4. Turn pressure control knob to low. Refer to Fig. 4.

5. Open the prime valve to the open - "Priming Position". This will allow an easy start. Refer to Fig. 3.

6. Turn the engine ON/OFF switch to ON.

7. Move the choke toward the closed position as per Fig.5.

8. Move the throttle lever slightly to the left as per Fig.5.

9. Turn the fuel valve ON as per Fig. 5. Pull the start rope. Pull the engine over against compression stroke and then let the rope rewind slowly into the starter. Pull rmly and rapidly to start the engine. Do NOT drop the rope. Hold on to the handle while rewinding, or the rope may rewind improperly and jam the assembly. If the engine does not start, open the choke a little more. If the engine oods, open the choke all the way and continue cranking.

10. After the engine is warm, gradually close the choke, raise the RPM of engine slightly by moving throttle to the left. Close the prime valve. Refer to Fig. 3

WARNING: To reduce the risk of static sparking, which

can cause re or explosion, always hold a metal part of the gun rmly against the metal pail when ushing. This also reduces splashing. Refer to Fig 6.

STARTING UP

1. LEARN THE FUNCTIONS OF THE CONTROLS.

PRIME/PRESSURE (PR) RELIEF VALVE is used to prime pump and to relieve pressure from gun, hose and tip.

(Prime/PR Valve) Used to relieve pressure from gun, hose & tip and to primethe unit when in OPEN position. (It is in open positionwhen there is a wider gap between valve handle and cam body.)

When in CLOSED position,there is only a very slight gap between handle & body. When closed the system is pressurized. Handle as a loaded rearm!

PRESSURE CONTROL KNOB is used to adjust pressure. Turn clockwise (CW) to increase pressure and counterclockwise (CCW) to decrease pressure.

2. PREPARE THE MATERIAL

a. Prepare the material according to the material

manufacturer's recommendations.

b. Place the suction tube into the material container.

c. If more coverage is needed, use a larger tip rather than

increasing the pressure.

d. Check the spray pattern. The tip size and angle

determines the pattern width and ow rate.

FOLLOW THE "PRESSURE RELIEF PROCEDURE".

To reduce the risk of injection, never hold your hand, body, ngers or hand in a rag in front of the spray tip when cleaning or checking for a cleared tip. Always point the gun toward the ground or into a waste container when checking to see if the tip is cleared or when using a self-cleaning tip.

When you spray into the paint bucket, always use the lowest spray pressure and maintain rm metal to metal contact between gun and container.

To stop the unit in an emergency, turn the engine off. Then relieve the uid pressure in the pump and hose as instructed in the Pressure Relief Procedure.

5. WHEN SHUTTING OFF THE SPRAYER

3. STARTING THE SPRAYER

a. Prime/PR Valve must be "OPEN" in the priming

position.

b. When you have ensured that the gun safety latch is

engaged, attach tip and safety guard.

c. Turn the engine ON/OFF switch to the "ON"

position. Pull rope vigorously until engine starts.

d. Turn Pressure Control Knob clockwise to prime the

pump.

e. After the pump is primed, turn Prime/PR Valve to the

"Closed" position.

f. Turn Pressure Control Knob to the desired spray

pressure.

g. Disengage the gun safety latch and you are ready to

spray.

4. ADJUSTING THE PRESSURE

a. Turn the Pressure Control Knob Clockwise to increase

pressure and counterclockwise to decrease pressure.

b. Always use the lowest pressure necessary to completely

atomize the material.

NOTE: OPERATING THE SPRAYER AT HIGHER PRESSURE THAN NEEDED, WASTES MATERIAL, CAUSES EARLY TIP WEAR, AND SHORTENS SPRAYER LIFE.

a. Whenever you stop spraying, even for a short break,

follow the "Pressure Relief Procedure".

b. Clean the tip & gun as recommended in the seperate

Gun Manual supplied with the gun. c. Flush the sprayer at the end of each work day, if the material you are spraying is water-based, or if it could

harden in the sprayer overnight. See "Flushing". Use a

compatible solvent to ush, then ll the pump and hoses

with an oil based solvent such as mineral spirits. d. For long term shutdown or storage, refer to the

"Flushing" section of this manual.

Be sure to relieve pressure in the pump after lling with

Airlessco Pump Conditioner.

AVOIDING TIP CLOGS

There is an easy way to keep the outside of the tip clean from

material build up:

Every time you stop spraying, for even a minute, lock the gun

and submerge it into a small bucket of thinner suitable for the

material sprayed.

Thinner will dissolve the buildup of paint on the outside of tip,

tip guard and gun much more effectively if the paint doesn't

have time to dry out completely.

PRESSURE RELIEF PROCEDURE

IMPORTANT!

TO AVOID POSSIBLE SERIOUS BODY INJURY, ALWAYS FOLLOW THIS PROCEDURE WHENEVER THE SPRAYER IS SHUT OFF, WHEN CHECKING IT, WHEN INSTALLING, CHANGING OR CLEANING TIPS, WHENEVER YOU STOP SPRAYING, OR WHEN YOU ARE INSTRUCTED TO RELIEVE THE PRESSURE.

1. Engage the gun safety latch. Refer to the separate instruction manual provided with your gun on its safety features and how to engage safety latch.

2. Turn the unit off.

3. Disengage the gun safety latch and trigger the gun to relieve residual uid pressure.

HOLD METAL PART OF THE GUN IN CONTACT WITH GROUNDED METAL PAIL. USE MINIMUM PRESSURE !

4. Turn Prime/Pressure Relief Valve (PR Valve) to the open (priming) position to relieve residual uid pressure.

THERE WILL BE A WIDER GAP BETWEEN VALVE HANDLE AND CAM BODY WHEN IN OPEN POSITION. IN THE CLOSED POSITION THERE IS ONLY A VERY SLIGHT GAP.

NOTE: THE VALVE HANDLE CAN MOVE BOTH CLOCKWISE AND COUNTER CLOCKWISE AND CAN FACE DIFFERENT DIRECTIONS.

5. Re-engage gun safety latch and close Prime/Pressure Relief Valve.

If the SPRAY TIP OR HOSE IS CLOGGED, follow Step 1 through 5 above. Expect paint splashing into the bucket while relieving pressure during Step 4.

DAILY MAINTENANCE

1. Always stop the pump at the bottom of its stroke when you take a break or at the end of the day. This helps keep material from drying on the rod, damaging the packings.

2. Keep the displacement pump packing nut/wet cup 1/3 full of Airlessco Throat Seal Oil at all times. The TSO helps protect the packings and rod.

3. Lubricate Connecting Rod Pin every 3 months.

4. Inspect the packing nut daily. Your paint pump has Airlessco's patented "Triple Life Packing System". Packing life will be extended a minimum of 3 times if the proper packing tightening procedure is followed!

If you suspect that pressure hasn't been relieved due to damaged Prime/Pressure Relief Valve or other reason, engage the gun safety latch and take your unit to an authorized Airlessco Service Center.

PACKING TIGHTENING PROCEDURE: Inspect the packing nut daily!If seepage of paint into the packing nut and/ or movement of the piston upward is found (while not spraying), the packing nut should be tightened enough to stop leakage only, but not any tighter. OVERTIGHTENING WILL DAMAGE THE PACKINGS and reduce the packing life to the life of other piston pumps.
